Is Your AC Ready for Summer? A Spring Maintenance Checklist

May 12, 2025

Keep Your Cool All Season Long with These Essential Tips

As the temperatures begin to climb, the last thing you want is to discover your air conditioner isn’t up to the task. At Custom Cooling & Heating, we know just how important it is to have a reliable, efficient AC system before the summer heat hits full force. That’s why we’ve put together this handy spring maintenance checklist—to help you stay ahead of the curve and ensure your comfort all season long. 


1. Replace or Clean Your Air Filters 

Dirty filters can restrict airflow, reduce efficiency, and even lead to system breakdowns. Check your filters monthly and replace them at least every 1–3 months—more often if you have pets or allergies.   Please avoid highly restrictive filters where the media feels or looks like paper. 


2. Clear the Area Around Your Outdoor Unit 

Over the winter, leaves, branches, and other debris can pile up around your outdoor condenser unit. Make sure there’s at least 2 feet of clear space around it to allow for proper airflow and unit to be able to discharge the heat from your home into the outside air. 


3. Check Your Thermostat 

Now’s a great time to test your thermostat. Make sure it’s accurately reading your home’s temperature and set to cooling mode. Consider upgrading to a programmable or smart thermostat to boost efficiency, reduce energy bills or allow control remotely or Geo-fencing. 


4. Inspect Ductwork and Vents 

Leaks or blockages in your ductwork can waste energy and leave parts of your home uncomfortably warm. Look for visible gaps, listen for whistling sounds, and make sure all vents are open and unobstructed. 


5. Examine the Drain Line 

Your AC system pulls moisture from the air, and that water needs somewhere to go. Check your condensate drain line for clogs, which can cause water damage or system shutdowns if left untreated.  If your condensate line was originally a clear vinyl hose and it is dirty or discolored, then replace it to allow you to see future potential clogs or blockages. 


6. Look (and Listen) for Warning Signs 

Unusual noises, warm air blowing from vents, or uneven cooling throughout your home can all be signs that your system needs attention. Don’t ignore the warning signs—address them early to avoid bigger issues later. 


7. Schedule a Professional Tune-Up 

Even if everything seems fine, a spring tune-up by an HVAC professional is one of the best ways to keep your system running smoothly. At Custom Cooling & Heating, our experienced technicians will check refrigerant levels, tighten connections, clean, check & lubricate applicable parts, and more to ensure your AC is ready for the summer demand.

The Benefits of Home Zoning Systems

April 25, 2025
Achieving the perfect indoor climate in every room of your home can be a challenge, especially when different family members have varying temperature preferences. If you find yourself constantly adjusting the thermostat to accommodate different areas of your home, a home zoning system could be the solution you need. At Custom Cooling & Heating, we specialize in innovative HVAC solutions , including home zoning systems, to provide enhanced comfort, energy efficiency, and cost savings. What is a Home Zoning System? A home zoning system divides your house into multiple climate-controlled areas, allowing you to set different temperatures for each zone. This system utilizes dampers within the ductwork and individual thermostats for each zone, giving you precise control over your home’s heating and cooling. Whether you want to cool the upstairs bedrooms while keeping the downstairs warmer, or adjust temperatures based on room usage, a zoning system makes it possible. Due to each home having a different duct design, Custom Cooling & Heating, INC will perform an onsite evaluation of the duct system and offer specific solutions for your system. Key Benefits of Home Zoning Systems 1. Enhanced Comfort for Every Room Traditional HVAC systems often create temperature inconsistencies, making some areas too hot or too cold. Zoning systems allow for customized climate control, ensuring every room stays at a comfortable temperature for its occupants. 2. Increased Energy Efficiency With a home zoning system, you can direct heating and cooling only where it’s needed, reducing energy waste. By not conditioning unoccupied areas, your HVAC system operates more efficiently, leading to lower energy consumption. 3. Lower Utility Bills By using energy more effectively, a zoning system can significantly cut down your monthly heating and cooling costs. According to the U.S. Department of Energy , homeowners can save up to 30% on energy bills with a properly installed zoning system. 4. Prolonged HVAC System Lifespan A traditional HVAC system works harder to maintain a uniform temperature throughout the entire home, leading to more wear and tear. A zoning system reduces strain on your HVAC unit, helping to extend its lifespan and reduce the need for frequent repairs. 5. Personalized Temperature Control Each zone in your home will have its own thermostat, allowing family members to set their preferred temperatures in different areas. This eliminates thermostat battles and ensures comfort for everyone. 6. Ideal for Multi-Story Homes & Large Spaces Homes with multiple floors often experience temperature imbalances. A zoning system helps regulate temperatures more effectively, keeping upper floors from getting too warm in the summer or too cold in the winter. Is a Home Zoning System Right for You? A home zoning system is ideal for homeowners who: Live in a 2-story home and are not comfortable on the 2nd floor Have rooms that are rarely used and don’t need constant heating or cooling. Experience noticeable temperature differences between floors or rooms. Want to reduce energy waste and lower their utility bills. Have family members with different temperature preferences. Experience the Benefits with Custom Cooling & Heating At Custom Cooling & Heating, we specialize in designing and installing home zoning systems tailored to your needs.
